Image distribution

[sbauch]

I initially installed https://github.com/jareware/chilipie-kiosk as the image and used their customization flow to do things like specify the URL.

But I ended up also adding some things - python based script to set the timezone from the network for instance. For my local usage, I used macOS Disk Utility to create an image from the SD card I had used when installing additional software and making further customizations. I can use that to flash additional SD cards with everything properly setup.

That image is however extremely large - 30GB. I don't think there's really 30 GB of important things on there, but am pretty clueless about how to create an image that has all my customizations and end up with an .iso more similar in size to the forked project (800 MB).
